American and german Armored cars and halftracks are good for a change.. some of the kits are quite good like Tamiya's M8 (which i've done) and M20.. simular and waiting on the build pile.. Any Dragon/DML 250 haftrack.. a challange but comes out great.. the new Dragon 3 in one kits are suppose to be awesome from what i hear.. ..
Some of the older kits can be had fairly cheaply if your frugal.. the 223 and 222 armored cars.. british daimler armored car.. SAS Jeep.. British long range desert recon truck... the german Horch 4x4.. ect there are many 1/35 non tank kits out there..
Or if you like tanks but want something different you could try Academys Tiger with the full inteirer.. (waiting on the shelf till i think my skills are good enough.. or Academys M10, or M18 Tank Destoryers.. Like tanks but with interiers...
I'm just starting Tamiya's duce and a half.. CCKW 353 for the move it campain myself.. as soon as i finish up this wingy thing i'm working on..
